+# Git Configuration
+
+Optimized Git configuration with useful aliases and settings for enhanced workflow.
+
+## Features
+
+- **Comprehensive Aliases**: Shortcuts for common Git operations
+- **Better Diff Algorithm**: Histogram algorithm for cleaner diffs
+- **Auto-correction**: Automatically fixes typos in Git commands
+- **Smart Defaults**: Optimized settings for better performance on Windows
+- **Global Gitignore**: Ignore common system and IDE files across all repositories
+
+## Installation
+
+### Configure Git
+
+```powershell
+# Copy the config to your home directory
+Copy-Item git\.gitconfig ~\.gitconfig
+
+# Configure global gitignore
+git config --global core.excludesfile ~/.gitignore_global
+Copy-Item git\.gitignore_global ~\.gitignore_global
+
+# Set your user information
+git config --global user.name "Your Name"
+git config --global user.email "your.email@example.com"
+```
+
+## Useful Aliases
+
+### Basic Operations
+- `git st` - Status
+- `git co` - Checkout
+- `git br` - Branch
+- `git cm "message"` - Commit with message
+- `git ca` - Amend last commit
+- `git can` - Amend last commit without editing message
+
+### Logs
+- `git lg` - Beautiful graph log
+- `git lga` - Beautiful graph log (all branches)
+- `git last` - Show last commit with stats
+
+### Branch Management
+- `git brd <branch>` - Delete branch (safe)
+- `git brD <branch>` - Force delete branch
+- `git bra` - List all branches (including remote)
+
+### Stash Operations
+- `git sl` - Stash list
+- `git sa` - Stash apply
+- `git ss "message"` - Stash save with message
+- `git sp` - Stash pop
+- `git sd` - Stash drop
+
+### Advanced Workflows
+- `git sync` - Fetch and rebase current branch
+- `git cleanup` - Delete all merged branches (except main/master/develop)
+- `git wip` - Quick work-in-progress commit
+- `git unwip` - Undo the last WIP commit
+- `git unstage <file>` - Unstage file
+- `git undo` - Undo last commit (keep changes)
+
+### Information
+- `git aliases` - List all configured aliases
+- `git contributors` - List contributors with commit counts
+- `git ignored` - List ignored files
+- `git untracked` - List untracked files
+
+## Configuration Highlights
+
+### Performance
+- `core.fscache = true` - Cache file system operations
+- `core.preloadindex = true` - Parallel index preload
+
+### Auto-stash
+- Automatically stash changes before rebase
+
+### Better Diffs
+- Histogram algorithm for cleaner diffs
+- Detect renames and copies
+- Show conflict markers in diff3 style
+
+### Smart Defaults
+- Auto-prune deleted remote branches
+- Rebase instead of merge on pull
+- Push current branch by default
+- Auto-correct typos in commands
+
+## Windows-Specific Settings
+
+- `core.autocrlf = true` - Handle line endings automatically
+- `credential.helper = wincred` - Use Windows Credential Manager
+- `core.editor = nvim` - Use Neovim as default editor
+
+## Global Gitignore
+
+The `.gitignore_global` file ignores common files across all your repositories:
+- System files (Windows, macOS, Linux)
+- IDE and editor files (.vscode, .idea, etc.)
+- Language-specific files (node_modules, __pycache__, etc.)
+- Temporary and backup files
+
+## Customization
+
+Edit `~\.gitconfig` to customize settings to your preferences. Remember to update your user information:
+
+```powershell
+git config --global user.name "Your Name"
+git config --global user.email "your.email@example.com"
+```
